Sleep polygraph and questionnaire data of 18 chronic primary insomniacs were compared with those of 18 age- and sex-matched controls. The insomniacs had significantly longer sleep latencies, less total sleep, less sleep efficiency, more terminal wake time, and less delta sleep. There were significant discrepancies between the insomniacs' and controls' subjective assessments of their sleep and the sleep-polygraph data, but in opposite directions. The insomniacs' recorded sleep also showed more night-to-night variability than that of the controls. However, the controls, in contrast to the insomniacs, reported sleeping worse in the laboratory than at home. Significant differences between insomnia subtypes validly reflected the insomniacs' subjective complaints and were generally in accord with expectations based on them.
将18名慢性原发性失眠症患者的睡眠多导记录图和问卷调查数据与18名年龄和性别匹配的对照组进行比较。失眠症患者的入睡潜伏期明显更长，总睡眠时间更少，睡眠效率更低，夜间觉醒时间更长，慢波睡眠更少。失眠症患者和对照组对其睡眠的主观评估与睡眠多导记录图数据之间存在显著差异，但方向相反。失眠症患者记录的睡眠在夜间的变异性也比对照组更大。然而，与失眠症患者不同的是，对照组报告在实验室的睡眠比在家中更差。失眠亚型之间的显著差异有效地反映了失眠症患者的主观抱怨，并且总体上与基于这些抱怨的预期一致。
